7 Application filed November 27, 1925. Serial No. -7 1,6l6i

This invention relates to combination door retainers (known in the trade as dovetails) and bumpers, particularly adapted for use between the door and its frame in an automobile or other vehicleto prevent shock attendant upon the closing of the door, and to prevent rattling or other relative movements of the door in its closed position.

The description so far as concerns sub ect matter relative to the retaining member, may

be found in greater detail in my application Serial N 0. 62,497, filed October 15, 1925.

It is apparent that in combining .these heretofore separate elements (dovetail and bumper) into one, the cost of manufacturing and the cost of installation are greatly lessened. It is also believed that the positioning of these elements in such relation, will effect more desirable results.

One of the objects of my invention is to provide a combination door retainer and bumper of a design which will be relatively simple in form andinexpensive to manufacture.

A further object of my invention is to provide a combination door retainer and bumper of a design which will be easily and inexpensively installed.

A further object of my invention is to 3 provide a combination door retainer and bumper in which the members in combination are arranged in such a relation as to more effectually eliminate rattling, the retainer member eliminating any vertical movement of the door and the bumper member eliminating any horizontal movement of the door.

Other objects and advantages will be apparent from the accompanying drawings, in

which: v

Figure 1 is a vertical, sectional view through my device in a closed position when mounted in the door and frame member;

Fig. 2 is a horizontal sectional view taken on the line 22 of Fig. 1,'showing the door in a partially open position; and

Fig. 3 is a perspective view of the resilien tongue and bumper members.

Referring to the drawings in detail, the

construction shown therein comprises a yielding, resilient, projecting device 10 of spring steel material secured to the swinging edge of the door 11; a rubber bumper 12 mounted within the projecting device, and a resilient receiving device 13 secured in a recess in the door frame 14.

The resilient projecting device is formed of a single piece of sheet material shaped to provide two leaf spring members 15, and a common base portion 16 uniting the leaf spring members, said base portion being suitably mounted into the body portion'of the door by means of screws 16. The holes in the base portion, through which the screws project, are formed by stamping a larger hole in the bottom thickness of the metal and a smaller hole in the upper thickness of the metal and pressing the overlapping portion of the smaller diameter into the larger hole. This provides a conical shaped seat for the head of the screw thereby eliminating the otherwise necessary operation of countersinking the hole. e

Between the two leaf spring members 15, is held the securing portion or stem 17 of the rubber bumper 12, this securlng portion being of a shape to conform to the contour of the leaf spring members and of sufiicient size to make a snug fit. At one end of the secur-' ing portion of the bumper and formed inte grally therewith is an elongated cushioning portion or head 18 adapted to seat itself'between the casing of thereceiving device 13 anda flange 19 of the door, upon the closing of the door. This cushioning portion is of a sufiicient width to hold in a somewhat spaced relation the door and its frame, thereby relieving the shock attendant upon the closing of the door.

The receiving device comprises a stamped sheet metal casing 20, seated in a recess in the door frame 14 and having upper and lower compartments in which are seated a pair of fiber blocks 21, suitably held in position and spaced a suflicient distance apart to snugly receive the leaf spring portions and bumper of the projecting member when the dooris closed. This action results injcompressing the leaf spring memberstoward each other,

which action also compresses the securing portion of the bumper member, thereby giv- ,ing more body or resistance to the leaf spring members. p V

It is apparent that in closing the door the resiliency of the elongated cushioning portion of the rubber bumper will absorb the shock attendant on its closing and that while in the closed position, the resilient projecting device held between the two fiber blocks of the receiving member, will effectively prevent rattling due-to vertical movement between the door and its frame member, while the bumper member will effectively prevent ra tling due to horizontal movements between v to the details thereof, as various other equivalent structures will be apparent to one skilled in the art and consequently the inventionis to be limited only by the scope of the appendedclaims. I

I claim f 1. The con'ibination with the hinged side door vof an automobile, said door being. provided with a flange at, its edge, of a yielding dovetail construction comprising areceiving device, a projecting spring device which snug ly engages said receivin device, said pros jecting device having a recess thereinand a bumper member having a securing portion held in said recess and a cushioning portion backed up by the flangeon said door.

2. The combination with the hinged side door of an automobile, said door being provided with a flange at its edge, of. a yielding dovetail construction comprising a receiving device, a proj ecting spring device which snug; 1y engages said receiving device and a bumper backed up by said flangeand engaging the receving device of said yielding dovetail con-i struction when door is closed.

3. The combination with the hinged door of an. automobile mounted. to swing about a substantially vertical axis and its frame of a yielding dovetail construction comprising a receiving device and a-proj ecting device which engages the receiving device when the door is closed, said projecting device comprising a pair of springtongues yieldable vertically about axes transverse to the plane of the door toiinove toward. and. from each other, and a cushioning body of yieldable material interposed between said ,spring tongues thereby giving more resistance to the springmembers,

4:. A yielding dovetail construction for combination with the hinged door oi an automobile mounted to swing about a substantially vertical ax s, said construct on compr sing pro ecting device a receiving device and a which engages the receiving device when the door is closed, said projecting device comprising a pair or spring tongues. 'yieldable vertically about axes transverse to the plane 1' the door to move toward and, from -each.

other, and a cushioning body ofyieldable material interposed between said spring,

tongues thereby giving more resistance to the spring members.

In witness whereorfll have hereunto. subscribed my name.
